Key Features

Designed for high strength and durability, the ARP Main Stud Kit offers several key benefits:

• Manufactured from 8740 chromoly steel for exceptional strength
• Heat-treated in-house to a 190,000 psi tensile-strength rating
• Precision J-form rolled threads for superior thread integrity
• Includes hardened, parallel-ground washers for consistent load distribution
• High-quality nuts for secure fastening and long-lasting performance
• Engineered to prevent main cap walk and fretting in high-stress conditions
• Suitable for use in a range of Toyota engines from 2002-2011

Construction & Design

The studs are crafted from 8740 chromoly steel, a material known for its excellent strength-to-weight ratio and fatigue resistance. The heat-treatment process enhances tensile strength, ensuring the studs can withstand the stresses of high-performance or heavily modified engines. The precision rolled J-form threads provide a stronger, more reliable thread engagement compared to cut threads, reducing the risk of stripping or failure during installation and operation.

Installation & Fitment

Installation requires proper torque specifications and should be performed by qualified technicians familiar with engine assembly. Fitment is designed to match the original main cap bolt locations for Toyota Camry, Scion tC, and Matrix models from 2002 to 2011. Verify fitment against your vehicle's specifications and part number before installation.

What’s Included

The kit includes all necessary studs, hardened washers, and nuts needed for a complete upgrade of your engine's main cap fasteners, ensuring a secure and reliable fitment.
